US markets split as chip stocks crash on AI regulation fears, oil rebounds

Key points

• The Dow Jones Industrial Average rose 0.6% to 53,650, while the S&P 500 fell 0.4% and the Nasdaq Composite dropped 1.1%.
• Semiconductor stocks plummeted, with Qualcomm falling over 10% and Nvidia down nearly 4%, amid fears of new AI infrastructure restrictions.
• Oil prices rebounded, with Brent crude rising to $97 per barrel and WTI crude reaching $89, reversing a sharp Wednesday decline.
• Challenger, Gray & Christmas reported October layoff plans fell to the lowest level since 2023, with 43,994 job cuts announced.
• The Bank of England raised interest rates by 25 basis points to 4%, its first hike since 2023, citing inflationary pressures from the Iran war.

Background

This volatility follows a massive 1,500-point surge in the Dow on Wednesday, triggered by Democratic victories in the midterm elections. Prior to the election, markets had seen a rotation toward tech and AI names, with the S&P 500 approaching record highs in September and October. The current divergence highlights a shift in investor sentiment from broad relief to sector-specific concerns regarding AI regulation and energy costs.

How outlets are covering it

Outlets agree on the sharp divergence between the Dow and tech-heavy indices, but emphasize different drivers. Yahoo Finance and CNBC highlight the rotation away from AI infrastructure due to Democratic control of Congress, noting specific losses in chipmakers like Qualcomm and Nvidia. Investing.com focuses on the 'bear market' for chip stocks, noting the Philadelphia Semiconductor Index has fallen over 20% since October. The Financial Times emphasizes the global impact, noting European bonds rallied and European stocks approached record highs as investors bet on constrained US policy. All sources attribute the oil price rebound to uncertainty over the Iran war, with CNBC noting Brent crude had fallen below $100 on Wednesday before recovering.

Why it matters

The divergence signals a potential regime change in market leadership, moving from AI-driven growth to value and defensive sectors. The prospect of stricter AI regulation could reshape capital allocation for hyperscalers and chipmakers. Additionally, the rebound in oil prices and the Bank of England's rate hike suggest inflationary pressures remain a concern, potentially influencing Federal Reserve decisions and global monetary policy.

What to watch

Investors will watch Friday's nonfarm payrolls report for labor market resilience, which could influence Federal Reserve rate decisions. Earnings from Duke Energy, Airbnb, and Lumentum are due, alongside weekly jobless claims data. The trajectory of oil prices and semiconductor stocks will be key indicators of market sentiment regarding AI regulation and geopolitical risks.
